[0031] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.
[0032] figure 1 It is a general flowchart of the method for optimizing wireless broadcast data delay access proposed by the present invention, including the following steps:
[0033] Step 1, assuming that the data set to be broadcast consists of s data items, that is, d 1 , d 2 ,... d s , for any data item d i , the probability of being visited is p i , let p 1 ≥p 2 ≥…≥p s , arrange all data items to be broadcast in descending order of access probability, that is, from hot data to unpopular data, assuming that the broadcast time of any data item is a time slot unit t, in a broadcast cycle, a certain data item d i The number of repeated broadcasts is f i , satisfying f 1 ≥ f 2 ≥...≥f s and f s = 1, the number of repeated broadcasts of popular data items is greater than that of unpopular data items, and each data item is broadcast at lea...
